8. Electric Connection
The electrical connection must be made by a specialist.
To avoid short circuits and resulting damage to the product, the negative pole
(earth) of the on-board battery must be disconnected during connection.
Only connect the negative pole of the on-board battery when you have completely
connected the device and checked the connections.
Observe the notes of the vehicle manufacturer to prevent loss of the stored
vehicle data (time, radio stations, etc.).
You should only use a voltmeter or a diode test lamp for checking the voltage on
the on-board cables as normal test lamps consume excessive currents and can
thus damage the electronic system of the car.
Adhesive techniques which become ever more common and painted metal parts
impair the electric conductivity. Therefore, not every metal part is a suitable
earthing point.
When laying the cables, make sure that they are not squeezed or scoured on
sharp edges. Use rubber grommets for the feed-though points.
When placing the lines in door pillars, etc., ensure that you do not impair any
safety-relevant devices (e.g. side airbags). The lines must not be placed in the
airbag trigger area.
Cut-and-clamp connectors are included to connect the open line ends to the vehicle
cable trunk.
• Place the line to which the connection is to be made in the cut-and-clamp connector.
• Then put the cable to be connected into the connector as well.
• Close the connector. You may carefully compress it with pliers until it latches.
